Abstract

The invention provides a method for dynamically monitoring urban traffic discharge pollution conditions based on taxi GPS data, and belongs to the technical field of atmospheric environment monitoring. The present invention firstly collects the taxi GPS data, the proportion of each vehicle type of different road types and the daily change of the taxi proportion; divides the collected GPS data into grids based on GIS, and then calculates the traffic volume and average speed of each grid , pollutant emissions; select the traffic volume, average speed, pollutant discharge and road length of each grid as monitoring factors, and calculate the monitoring index value of each grid according to the weight of each monitoring factor, and finally according to the monitoring index value Determine the traffic emission pollution status level of each grid. The invention solves the problem of low accuracy of real-time monitoring data of traffic emission pollution status in the prior art. The invention can be used for monitoring the urban traffic emission pollution status.

Description

technical field

[0001] The invention belongs to the technical field of atmospheric environment monitoring, and in particular relates to a method for dynamically monitoring urban traffic discharge pollution conditions. Background technique

[0002] With the rapid development of social economy and the rapid growth of the number of motor vehicles, motor vehicle exhaust pollution in urban areas has increasingly become one of the main sources of air pollution in cities. The increasing traffic emission pollution year by year not only destroys the urban environment, but also poses a serious threat to the health of residents. Therefore, it is imperative to realize the monitoring of urban traffic emission pollution and to take effective measures to manage and control motor vehicle exhaust pollution.

[0003] At present, many cities in China use the annual average mileage method to estimate the total amount of motor vehicle exhaust emissions, and have established their own inventorie...
